Answer:
The area of each section of the circle is ![25\pi\ m^{2}](https://tex.z-dn.net/?f=25%5Cpi%5C%20m%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of a circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
![r=10\ m](https://tex.z-dn.net/?f=r%3D10%5C%20m)
substitute
![A=\pi (10^{2})=100\pi\ m^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%2810%5E%7B2%7D%29%3D100%5Cpi%5C%20m%5E%7B2%7D)
To find the area of each section divide the complete area of the circle by ![4](https://tex.z-dn.net/?f=4)
so
![100\pi\ m^{2}/4=25\pi\ m^{2}](https://tex.z-dn.net/?f=100%5Cpi%5C%20m%5E%7B2%7D%2F4%3D25%5Cpi%5C%20m%5E%7B2%7D)
Just divide 28 by 15
and you get
1.866666666666667
